1. 'The DS-EQ1 uses a switching power supply, which results in a peak at roughly 70kHz (see FFTs below). Our typical bandwidth filter setting of 10Hz-90kHz was maintained for THD measurements; however, for noise and THD+N measurements, a 10Hz-45kHz bandwidth was used, to ignore the 70kHz peak.'


Should I be concerned about possible IMD, etc. effects that the FR and noise peaks in the 70kHz range have on down stream electronics? Even my SACD player rolls off -3db at 50kHz.

2. I am interested in how the DS-EQ2 compares on the test bench. Thank you.
